This paper introduces a novel high gain DC-DC converter topology which can be used for photovoltaic (PV) applications. The proposed DC-DC converter consists of 3 interleaved boost converters and 2 voltage multiplier cells (VMC). The operating principle, characteristic waveforms, design details along with the simulation results prove the validity of the design and its superiority over existing converter topologies in terms of its ability to provide high voltage gain at higher power level and low device stress. The proposed topology is able to produce a voltage gain of 10 and deliver 3kW output power at 88% efficiency. © 2013 IEEE.

This study proposes a novel non-isolated high-gain high-power DC-DC converter. The converter is developed from a basic high-gain high-power converter structure. The proposed converter comprises of a three-phase interleaved boost converter, one coupled inductor and a voltage multiplier cell which act as gain extension stage. The main desirable features like voltage gain, stress on the switches and diodes, turns ratio, component utilisation factor and efficiency are summarised. The power circuit, operational details, simulation and experimental results of the 60 V/1.1 kV, 3 kW, 100 kHz proposed converter are presented. © The Institution of Engineering and Technology 2016.

Transformerless high-gain DC–DC converter for microgrids

The output voltage available from renewable sources like photovoltaic panels, fuel cells and battery banks are too low to be practically utilised. Therefore, the available voltage must be stepped up considerably before connecting to the load. In this paper, a novel topology, which consists of two interleaved stages and five voltage multiplier cells, is presented. The topology is derived from a classical boost converter and utilises two switches, two inductors for the interleave stage,12 diodes, 12 capacitors and one voltage lift capacitor to provide a voltage gain of 14. In general, a topology that provides a gain (N + 2) times that of a classical boost converter utilises (2N + 2) diodes and (2N + 2) capacitors along with a voltage lift capacitor. The primary feature of this topology is its capability to provide high-conversion ratio without using a transformer; additional features are, continuous input current, moderate duty cycle operation and modularity. Experimental results obtained from a 100 W, 24 V/336 V prototype demonstrate the feasibility of the converter and validate the converter design. © 2014 Inderscience Enterprises Ltd.
